   You can't know where your data is placed. It's an SD card, not a flash
disk.

   At least in my FR, the battery sits loose enough in the battery
compartment that it does not maintain contact with the battery connector
when dropped 1.4 m onto gravel. Thus if the SD card might get fubared by
sudden removal of power, it might also get fubared by a g-shock.

   IIRC:

# flash_eraseall /dev/mtd6

(Check your /proc/partitions - you wan't the largest one.)
